Google has released Android 5.0.2 Lollipop over-the-air update for its 10in Nexus tablet codenamed mantaray, following the availability of the factory images last week. The new stock firmware moves the build number of the Nexus tablet from LRX22C to LRX22G.

If you have not received the OTA notification yet on your Nexus 10 tablet, you can flash the update directly using the OTA zip, which is now available. Check out the following step-by-step installation guide to manually update your Nexus 10 to Android 5.0.2 LRX22G Lollipop.

Key-points

Create a backup of all important data of the device using any custom recovery mode.

Step-2: If your Nexus 10 is rooted with custom recovery installed, then do the following;

Copy the OTA zip file to the internal storage of Nexus 10

Reboot the tablet into recovery mode

And install the zip file as you do for other flashable zip

Step-3: If your Nexus 10 is not rooted and running stock recovery, then do the following

Reboot the Nexus 9 in to recovery mode by holding Volume Down and Power buttons together for a few seconds. When you see the fastboot menu and Start, press Volume Up button for a few times until the Recovery appears on the screen. Now press Power button to enter recovery mode

Step-4: You should see an Android with a red exclamation mark on the screen. Press Volume Up and Power buttons together. You will be presented with a menu.

Select the second option from the menu which reads, apply update from adb

Step-5: Connect the Nexus 10 to the computer via USB cable

Ensure that you have the latest version of adb that supports the sideload command (If you don't download the Android SDK to ensure your adb is updated.)

Step-6: Open a command prompt (CMD in Windows, but regular shell if your system is running on Linux or Mac) in the same directory, where you have saved the downloaded zip file
